WWW::OAuth implements OAuth 1.0 request authentication according to RFC 5849 (sometimes referred to as OAuth 1.0A). It does not implement the user agent requests needed for the complete OAuth 1.0 authorization flow; it only prepares and signs requests, leaving the rest up to your application. It can authenticate requests for LWP::UserAgent, Mojo::UserAgent, HTTP::Tiny, and can be extended to operate on other types of requests.
